Diethylhydroxylamine (DEHA) is an organic compound with the formula (C2H5)2NOH. It is a colorless liquid, although it is usually encountered as a solution. It is mainly used as an oxygen scavenger in water treatment. Due to its volatility, it acts as an oxygen scavenger throughout the entire boiler system due to steam carryover. DEHA also reacts with ferrous metals to form a passivized film of magnetite throughout the boiler system. It also finds applications in: - Polymerization inhibitor - Color stabilizer (photographics) - Corrosion inhibitor - Discoloration inhibitor (phenolics).


  • Oxygen scavenger, corrosion inhibitor, polymerisation inhibitor
